what is the equivalent of -xM1(solaris compiler option) in gcc

what is the equivalent of -xM1(solaris compiler option) in gcc

[nagarjun]

I'm porting the C++ code from solaris to Linux.

Can anybody tell me what is the gcc equivalent of solaris -xM1 option.

In brief I have to replace */opt/SUNWspro/bin/CC -xM1* with *g++ with
equivalent option*

Thanks

It would help if you say what that option does for the Solaris compiler.

Got the following from solaris help doc:

Generates makefile dependencies like -xM, but excludes /usr/include files. 

For example:

more hello.c
#include<stdio.h>
main()
{
    (void)printf(“hello\n”);
}
cc– xM hello.c
hello.o: hello.c
hello.o: /usr/include/stdio.h

Compiling with -xM1 does not report header file dependencies:

cc– xM1 hello.c
hello.o: hello.c

If I remember right the -xM1 option is a Dependency Option.
Check the gcc manual for "PREPROCESSOR OPTIONS" -M{F,M,T,MD…}.

Cheers ingo
